In the United States, state and local authorities are in charge of
voting and the country uses more than a half dozen different voting technologies.
As a result, the country can't guarantee that it accurately counts national votes
in a timely fashion. This article discusses the problem and potential solutions to the U.S. voting dilemma.

The electoral college guarantees that each state gets both an equal vote and a vote proportional to its population. A national popular vote cannot guarantee either, without compelling all citizens to vote.

But is gives a voice to all the citizens. I say that is more important. We have moved beyond the original conception of what the states were suppose to be. We have become a nation-state rather than a nation made of states.
